julia: fix depends for -devel pkgs
julia: fix depends for -devel pkgs

julia needs the symbolic links libmpfr.so, liblapack.so, and libgit2.so
(at least) thus make it depend on the respective -devel packages.
Also enable i686-musl and x86_64-musl target architectures.

i686-musl currently fails because of missing setcontext(3) and
sigreturn(2) implementations for x86.

Closes: #10212
